This invention relates to meat stompers.

The general object of the invention is to provide an improved meat stomper for use in forcing meat to be ground into a grinding machine.

A more specific object of the invention is to provide a grinding machine having a meat stomper mounted thereon in such fashion that it may be moved to operative position when desired and when released will return to normal position.

Another object of the invention isto provide a meat grinding machine includinga motor control together with a meat stomper and wherein switch means is provided whereupon movement of the meat Stomper to operative position causesA the 15 control switch to the motor to be closed so that the motor will operate.

Other objects and the advantages of my invention will be apparent from the following description taken in connection with the accompanying 20 drawing, wherein:

Fig. 1 is a side elevation, partly in section, showing my Stomper;

Fig. 2 is a central, sectional view through the supporting bracket;

Fig. 3 is a fragmentary, sectional view showing the end of the support;

Fig. 4 is a side elevation, partly in section, showing a modified form of my invention;

Fig. 5 is a View taken on line 5-5 of Fig. 4;

Fig. 6 is a side elevation showing another modification of my invention; and

Fig. 7 is a central, sectional View showing a further modification.

In the practice of meat grinding it is customary 35 to provide a meat Stomper by means of which the pieces of meat to be ground are forced into the hopper by means of a Stomper and heretofore it has frequently happened that careless workmen will for various reasons fail to use the stomper 4 and will endeavor to force the meat into place with their fingers with frequent injury and it is my object to overcome this difficulty and also prevent misplacement of the Stomper and delays in securing the same.

Inv overcoming these difliculties I have devised a meat Stomper which is indicated generally, in the accompanying drawing, at III. As shown the Stomper is mounted on a meat grinder which is indicated generally at II and includes a motor housing I2 from which a sleeve I3 projects. Thissleeve has a reduced end I4. A grinding head is indicated at I5 and includes a hopper I6 and a sleeve Il which ts over the reduced end I4 of 55 the motor housing sleeve I3. The motor has a (Cl. 14S-182) shaft I8 thereon and the grinding head and motor may be connected through such means as a pair of coupling sleeves I9 and 26 although the features of such coupling form no part of the present invention.

A supporting bracket is indicated generally at 2l as comprising a pair of clamp members 22 and 23 which are held in place at the bottom by bolts 24, The upper ends of the members 22 and 23 engage a block 24 and are held upon theblock by screws 25. A clamping screw 26 passes through a projection 2l on the clamping member 22 and through aligned apertures in the sleeves I4 and I'I. This clamping screw serves to hold the removable grinder head upon the machine while the supporting bracket 2| serves to hold the Stomper upon the grinder head.

The block 24 is threaded as at 28 to receive a hollow tube 29 which is bent in the shape of a shepherds crook which is provided with a cap 3D at the free end. Secured Within the tube 2971s a spring 3|., one end of which is engaged by a removable fastening member 32 and the other end of which issecured at 33 to a flexible member 34 which may be of chain or wire.

This flexible member 34- at its other end engages the eye 36 of a swivel 31. This swivel 31 engages the end 38 of a harness snap 39. A rubber bumper member 40 may be arranged on the flexible member 34 adjacent the eye 36 as shown in Fig. 3. The harness snap 39 engages an eye 4I which is screwed into the end of a meat stomper 42. The meat stomper 4.2 may be made in. the usual shape of metal or Wood andincludes a handle portion 43 and an enlarged portion 44' having a meat engaging end 45.

-In use the operator starts the grinding machine and grasps the handle of the Stomper extending the spring and pulling the stomper down from the normalposition shown in Fig. 1. After using, the stomp is released and it immediately flies back to its position.

In Figs. 4 and 5 I show a modification of my I invention. In this modification the motor housing is indicated generally at 5D, and is provided with a sleeve 5I and a reduced portion 52 on which a sleeve 53 on the grinding portion 54 is mounted. The grinding portion 54 includes a hopper 55 and the arrangement of motor and grinder is similar to that previously described.

Mounted on the sleeve 53 is a switch housing 56 which includes downwardly projecting arms 51 which are secured together by bolts 58. The housing includes a switch 59 pivoted as at 63 45, work is iinished and then releases the Stomper which is urged downwardly in Fig. 5 by a spring 6! Vaway from spaced contacts 62 and 63 which may be connected in any suitable manner through leads 64 with the motor in the housing 50. The vswitch 59 is connected by a wire or other ilexible member 65 with a spring 65 arranged inV a tube 66 which may be similar in all respects to the tube 29 'previously'described The lower end of this tube 66 is threaded as V*at 61 in the top of theV switch housing. The spring 65' is connected by a flexible member 68 with a Stomper 69 which is similar to the construction previously described.

In operation the contact 63 is wired to a suitable 1 source of electricity and the parts are assembled in the position shown in Fig.-`4. MeatV is then-.

placed in the hopper 'and the operatorV grasps the Stomper V69 pulling down on the Stomper and thus moving the ilexible member 68 against the action of the spring V thus pulling the iiexible member 65 and swinging Vthe switch 59 about its pivot 6U until the contacts 62 andv 63'are Vbridged by the circuit closing portion 10 on the switch 59 so thatcurrent yis Suppliedrto the motor.V

Therzr grinding operation continues until the operator has nished theY work whereupon he releases the Stomper 69 and the spring 65 thereupon pulls the Stomper into released position.

YThe tension -ofV the spring 6| is such that in theposition in the drawing this spring 6l overcomes the tension of the spring 65 and pulls the switch 59 to the position shown in Fig. 5

so that the circuit is broken. Y V

InY Fig. v6 the Vmotor housing I2, sleeve I3,

' grinder head |5, and hopper I6 are as previ- Vously described, also the tube 29 is the same as that described in connection with Fig. 1.

Y Y this construction the end of the tube 29 is provided with a cap 15 on which. an eye 16 is secured'.VV On this eye isa flexible member shown as av chain which is connected to a spring 18 whichis connected to a further flexiblemember 19`and the latterV is connected to a stOmper'BU. In use the operator grasps'the Stomper pulling it to position against the spring 18 until the whereupon the spring 18 pulls it out of the way.

In Fig. 7 I show a modification of -my invention wherein a bracket 85 supports a shaft 86 which inA turn supports a drum 81. The bracket 'inc1udesla lower varm 88 which Ysupportsa Y pulley 89. A coil spring is secured at its inner end to the shaft 86 and at its outer end to the e drum 81 and is so arranged Ythat it is'constantly YadjacentV the drum in a clockwise direction. VMounted on the drum is a ilexiblefmember 9| which passes on the pulley 89 and has a stomper 92 secured at its lower end. In use the bracket 85 is made with a suitable support over a meat hopper and the Stomper is grasped when it is Y desired to be used and is pulled against the tension of the spring lll!Y and when the grinding operation is finished it is released VYwhereupon it returns Yto position.
